I feel always page speed is part of googles algorithm because if the site not renders within stipulated time..surely it will be considered as technical issue from website respective. Even UX respective also not good if the pageloads ample of time

Thank you Kristina for sharing VIMP article at the right moment..because 2014 & coming years would be much more IMP for all companies to have a checklist in had whether ALL best practices are implemented or not..

If you build ALL the pages in mobile version then it would be much beneficial for SEO &UX respective rather than re-directing most of the pages Home / other pages itself..Always good to build lots of pages on mobiles where conversion%'s are creeping up YOY.

Very good interesting posting...Yes in my client websites also we have sent thousands of emails...Only received 10% link removals...but we have maintained them well in GD to show it to google..everyday we add unantural links in disavow file using ahrefs.com & weekly from GWT...which is reducing RISK of getting penalized...

We are nowhere impacted from last couple of months period of time following this.

I feel, still gaining links from Qualitative websites (respective industry specific) is considered by google even considering to guest posts as well..
